The concept of a characteristic reaction time is applied to the flocculation reaction and proposedfor use as a new guideline for the design of continuous flow flocculators. The proposedguideline suggests designing flocculators on the basis of the characteristic reaction time for theloss of one micrometer of particles in the suspension. Based on the current understanding offlocculation processes and classical chemical engineering design principles, this new guidelinehas several advantages over the currently accepted design guidelines. These advantages arediscussed in the paper and the new approach illustrated by comparison with the design of an operating watertreatment facility. Includes 9 references, tables, figures.
